There are growing concerns around the world about global warming issues, and the countermeasures to reduce global warming by greenhouse gases are proposed. In the transport sector, Electric vehicle (EV) is expected as one of solutions to reduce heavy dependence on oil and CO2 emissions in Japan. In order to promote large-scale diffusion of EV, it is necessary to build charging infrastructures where EV can be charged rapidly. In this research, we firstly evaluated daily EV charging load taking account of rapid charging at charging stations by using the traffic simulator. As the result, it was found that there is a possibility of balancing uncontrollable EV charging load and Photovoltaic (PV) output. Finally, the reduction effect of annual fuel cost in power grid was evaluated by controlling EV charge. In optimal charging pattern, the annual fuel cost is reduced about 40 billion yen. © 2013 The Institute of Electrical Engineers of Japan.
